Improved knife-cleaner



UNITED STATES PATENT OFFICE.

THOMAS M. FELL, OF BROOKLYN, NEW YORK, ASSIGNOR TO JOHN MATHER JONES, OF SAME PLACE.

IMPROVED KNIFE-CLEANER..

Specication forming part of Letters Patent No. 38,786, dated June 2, 1863.

To all whom it may concern:

Be it known that I, THOMAs M. FELL, of

Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use a certain new and useful ImprOvement in Knife-Cleaners; and I do hereby declare the following to be afull, clear, and exact description of my said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is a vertical crosssection of my knife-cleaner, and Fig. 2 is a section showing the knife in place for cleaning.

Similar marks of reference denote the same parts.

Knife-cleaners have heretofore been constructed with two cleaning-wheels face to face, kept together by a spring.

The nature of my said invention consists in a double rest taking the back of the knife on each side of the cleaning-disks, so that said knife is sustained, and the handle relieved from the strain heretofore usual, and which strain often breaks the handle off the bladf; and I apply a grinding-wheel to the said cleaning-disks, so as to sharpen the knives when necessary.

In the drawings, c is a standard secured in any convenient manner to a table or other article, and thisA standard carries a shaft, b, provided wit-h a crankhandle, c, by which it may be rotated. On this shaft is a fixed disk, d, and a yielding disk, e, kept toward d by the springj' around the shaft b, and g is a nut by which the pressure of said spring may be regulated. The surfaces of the disks d and e contiguous to each other are to be covered with felt, leather, or other suitable material, as at i i, and the usual cleaning powder 0r dust is to be introduced between these surfaces yby springing back the disk e.

The knife to be cleaned is placed under the overhanging rests k, with the back upward, and the point is entered between the cleaningsurfaces i i, and by rotating the disks by the handle c the said knife is cleaned, and at the same time drawn along until the back of the knife near the point rests beneath the overhanging block l. By this arrangement of rests k and l the knife-blade can be sustained, regardless of the handle, and when the knife is thoroughly cleaned it can' be drawn out from between the disks, or the said disks ro tated in the opposite direction, which slides the knives back.

The arrow indicates the direction in which the disks are to be rotated in cleaning.

The disk e is provided with a flange, lm, around which emery is -applied to make a grinding-ring at n, said emery being mixed with any suitable material to cause the particles to adhere together, or a ring of any suit-,

able grinding-stone may be applied at this point.

What I claim, and desire to secure by Letters Patent, is

1. The rotating cleaning-disks d and e, faced with felt or other suitable material, andkept together by a spring, in combination with the rests lo and l, taking the knife, as specified.

2. The grinding-ringo, applied as speciiied, in combination with the cleaning-disks l and e, for the purposes and as specified.

In witness whereof I have hereunto set my signature this 6th day of April, 1863.

Witnesses: THO. M. FELL.
